What Are The Necessary Cables For A New Hdtv, Direct Tv Installation?

Okay
Nice Setup BTW!
You will need:
Either an HDMI or (composite cables Y, Pb, Pr (red, green blue))
I suggest Composite cables becasue HDMI are prone to failure and if it fails it will be a pain to rewire. Composites are more reliable and will not affect your picture enough to notice.
If you have Dolby surrond sound you may also want to run an optical wire for the surround sound. The HD DVR will have a port, be care they break easy.
You’ll use the composite to connect the HD DVR to the tv and the optical to connect the HD DVR to the surround sound.
That should so do it!
As far as what Ryan B says- he has no information to back that up. I deal with this everyday, I am fluent with the technology, and while it is older, all the kinks with HDMI have not been worked out. here’s what I have:
In discussion with some industry engineers, I found that there are some problems popping up with the adaptation of the new HDMI standard. Here is what was discussed:
(1) Some cable TV boxes with HDMI out are not delivering any picture to displays with HDMI inputs.
(2) The current HDMI plug appears not to be as sturdy as anticipated, and there may be a change next year in the design of the plug, and the new plug would not fit in current HDMI sockets.
(3) If you have an HDMI source such as a DVD player, and connect it to your display via HDMI, you may not be able to get 5.1 digital bitstreams to come out of the coaxial or Toslink digital output of the player at the same time as digital video and audio out of the HDMI output.
(4) HDMI is a two-way digital communication, and some displays send a handshake signal to the DVD player that permanently messes up the player’s ability to output digital video through its HDMI jack.
(5) HDMI v 1.1 is already hitting the shelves, with v 1.2 on the way, and v 1.3 in the next couple of years (v 1.3 will deliver higher res 5.1 digital audio). What will be the backward compatibility of these versions?
In my own situation, using a DirecTV satellite box with HDMI out to an LCD TV with HDMI in, when I turn off the TV, the satellite box crashes. I have to unplug the satellite box and then plug it back in. I have not solved this problem, except by switching to some other input besides HDMI before turning the TV off. Then, when I turn the TV back on, I switch to the HDMI input for viewing.
